The lines are not the same as thehy have different slope and y-intercept.
As the slopes are different, they are not parallel.
If the slopes are negative reciprocals, the lines are perpendicular.
We can test it by:
[tex]m_2=-\frac{1}{m_1}=-\frac{1}{\frac{2}{3}}=-\frac{3}{2}[/tex]The slopes are negative reciprocals, so they are perpendicular.
Answer: C. The lines are perpendicular.
